MILLING ATTACHMENT FOR PUMPS.

SPECIFICATION forming part of Letters Patent No. 548,125, dated October15, 1895. Application filed November 26, 1894. Serial No. ,004- (N0model-) To aZZ whom it may concern.-

Be it known that I, WILLIAM MANN, residing at Hay Springs, in the countyof Sheridan and State of Nebraska, have invented certain usefulImprovements in Milling Attachments for Pumps; and I do hereby declarethat the following is a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, which form a part of this specification.

This invention has relation to a new and novel milling attachment moreparticularly adapted to be used in connection with a pump.

In the accompanying drawings, Figure 1 shows a central sectional View ofa reciprocating pump-rod provided with myimproved milling attachment,while Fig. 2 shows a side elevation of the hopper as detached.

A represents an ordinary disk, which forms part of the shaft 2, as isusually employed in windmills, the motion-imparting blades or vanesbeing secured to this shaft, as is usual in windmills. To the disk A, bymeans of a wrist-pin 3, is secured the usual reciprocating pump-rod 4',which extends down intovthe pump-well, as is well understood by thosefamiliar with the art. The aim of my invention is more particularly tomake this reciprocating pump-rod 4 perform a double function. Inaccomplishing this I provide this bar 4' with a series of conicalcollars B, which extend any suitable distance and form an integral partof the rod. These collars represent each the form of the frustum of acone, having its axis cut by two parallel planes oblique to the axis bywhich the cone is gen erated and the frusta placed coaxially one withanother to form acentral grinder. The angular portion, however,extending laterally and forming a sharp angle, as is shown at the pointsmarked 5, works within a suitable housing D, of any suitable metal, andis preferably made in two parts, having the con nectingflange 6, bymeans of which this two-part housing is connected. Interiorly I providethis housing, which is preferably conical, with a series of serrationsC, which serrations are preferably of an increasing diameter from thetop of each one to its bottom,but their angles 7 preferably being in ahorizontal plane. These angles form openings in the shape of a truncatedcone, the base forming the largest diameter. It will be noticed that thereciprocating rod B also forms, as it were, aseries of truncatedcone-sections, the lower edge of which, however, is at an angle to thatformed by the sections within the housing D. Above I provide thistwo-part housing with an ordinary hopper E, the whole being sustained bymeans of suitable brace-bars 10, forming partofabin F.Belowthisbinisprovided with an opening 12, through which the pump-rodextends into the well. These instrumentalities can be arranged at anypoint of the pumprod, it being, of course, understood that the pump-rodL is held and is simply guided in a reciprocating vertical position, theupper end of the pump-rod being provided with an ordinary joint. In thedrawings this joint is not shown, as it does not form any part of theinvention. When all the instrumentalities have been properly arranged,the operation of my device would be as follows:

The hopper E would be filled with any suitable grain to be milled, andas the pump-rod 4' would reciprocate it would gradually engage some ofthe kernels and carry them into the housing D, where the succeedingserrations B of the rod would successively engage the same and removeparts, which parts would, of course, be carried into the communicatingserrated opening, and so on down to the smallest opening, where it wouldissue in the form of a meal. pump-rod 4' I have provided a bracket K,extending from the housing D, as shown.

Now, having thus described my said invention, what I claim as new, anddesire to secure by United States Letters Patent, is-

In a milling attachment for pumps the combination with a pump rod, saidrod being provided with a succession of collars forming an integral partof said rod, said collars being in the form of the frustum of a conehaving its To further guide the axis cut by two parallel planes obliqueto the being providedabove with the hopper, E, all

axis by which the cone is generated, the frusta being placed coaxiallyone with another to form a central grinder, and the two part housing, D,said housing being provided with a series of serrations or conicalseatings, 0, their base being preferably in a horizontal plane, saidhousing being open-ended and substantially as and for the purpose setforth.

In testimony whereof I affix my signature in presence of two witnesses.
